Question

A developer's Lambda function currently writes plain-text log lines such as 'Processed order 12345 in 240ms'. The operations team wants to build CloudWatch Logs Insights queries and metric filters that can reliably extract the order ID, duration, and status without brittle string parsing. What is the MOST effective change the developer should make to the logging approach?

Accepted Answer

Emit each log entry as a single-line JSON object with named fields (e.g. orderId, durationMs, status) so downstream tools can parse and query discrete attributes.

Answer

Increase the Lambda memory allocation so logs are flushed to CloudWatch more quickly and become easier to parse.

Answer

Write logs across multiple lines per event with one attribute per line to make each value visually distinct.

Answer

Enable X-Ray active tracing so the log lines are automatically converted into structured segments.
